I'm trying to modelate snow falling on ground. My terrain is textured using one 2D grayscale texture for details and another 1D texture to apply color per height. When snowfalls get on terrain I want the terrain to slowly blend to white (geometry color).

You may need to do some stuff with the ALPHA channel also.
But that should get you going..

Sorry scratt, but I have written it wrong. I wanted to say Unit1 and Unit2, not Unit1 + Unit2(the effect obtained by modulating the 2 texture to blend it to white). Here is a scheme(now I'm trying to achieve the image from step 2).
